Heidenhain machine simulation

[jswickJ9PWC]

Hi all,

I have my machine modeled and looking good in machine simulation and it helps a lot to check with clearance in 3+1, but it doesn't appear able to simulate the machine in full fourth or fifth. The positioning is wrong (for example, if I'm milling at an angle, it will appear to be straight up) and there is no fourth or fifth axis movement simulation, even though I can move the axis in the machine model.

I know the simulation works by taking the post processor code and re-reading it, so is this a limitation on the ability to read Heidenhain code with TCPM?

I'm wondering if the machine kinematics for rotary motion were defined in the machine configuration.

Hello @jswickJ9PWC 

The simulation is not re-reading the gcode.

In fact, when simulating, the post engine is called in a specific way, to use callback functions for generating the animation.

But it does not generate nc-code, nor does it read the gcode.

The issue can be related to the axis definition in the machine.

In fourth axis machining, can your real machine use TCPM?

If so, have you configured the rotary axis as such ?

Is this a rotary axis on the head or the table?

Can you share the Fusion file and the machine configuration, eventually sending a;link via a private message?

This way, i will be able to look at any settings i need, instead of asking tons of questions.

Have a nice day.

Regards
